CR00011665 PRI 2 When using an unstructured TDM group over an E1 mode PRI interface,
occasionally a high level of errors was experienced. This may have caused the link
to be unstable, or may have resulted in reduced data throughput.
This issue has been resolved.

CR00011855 TCP,
UPnP
2 TCP sessions would sometimes “hang” in the Close Wait state. This behaviour
occurred when a UPnP notification session was closed by the control point
(usually Windows XP, SP2), via a “200 OK” message that contained a
“Connection: close” field, that also had the TCP/FIN flag set.
Because these TCP sessions were not closing, eventually all available TCP
resources could be used up, preventing new TCP sessions from opening.
This issue has been resolved. Such TCP sessions now close correctly.

CR00011907 IP Gateway 2 Previously, if the IP Helper attempted to redirect packets to an address that
matched the network broadcast address of the egress interface, the packets were
only forwarded if directedbroadcast=yes for the egress interface. By default,
directedbroadcast=no, so such packets were dropped.
This issue has been resolved. IP can now distinguish between packets redirected
by the IP Helper and real directed broadcast packets. If directedbroadcast=no,
IP still redirects packets from IP Helper when necessary.

CR00011991 WAN load
balancer
2 An issue occurred when the router accessed multiple WAN load balancer
healthcheck hosts, and was configured as a firewall that performed enhanced
NAT. Instead of testing the health of each healthcheck host through every WAN
LB resource (and therefore over all relevant WAN interfaces), the router only
tested through one WAN LB resource. If that one WAN interface lost connectivity
to the Internet, the WAN LB incorrectly thought that all WAN LB resources had
become unavailable.
This issue has been resolved. The WAN LB now correctly checks the health of all
healthcheck hosts through all WAN LB resource interfaces.
